tlie rims with corresponding ones having sprocket teeth set at a greaterpitch. The c` ain then again runs smoothly and efiiciently for anotherlon period. This opas many times as 'found practicable in., actual useto prolong the life of the chain,

The rim is rigid in form and may be readily applied to or removed fromthe pins and sliding the rim laterally on the periphery of the Wheel.

Having now what l claim as described my invention, new and desire tosecure le by Letters Patent, r is l. A sprocket wheel comprising a Wheelbedy having a recessed periphery, a removable rim of a rigid circularform carrying sprocket teeth and having lugs projecting andmvvedge meansfor fas tening the lugs therein.

2. A. sprocket Wheel comprising a 'Wheel body having a recess in itsperiphery, a re- Levine@ movable rim of rigid circular form carryingsprocket teeth and mounted on the periphery of the Wheel body With thecapacity of relative circumferential movement, a block secured to saidrim and extending into said recess, and a spring for transmittino` thestress between the block and the Wheel zbody.

3. A sprocket Wheel comprising a Wheel Abody having a chamber in itsperiphery, a

spring contained therein, a removable rim of rigid circular formcarrying sprocket teeth and mounted on the periphery of the wheel bodywith the capacity o'relative circumerential movement, and means rigidlysecured to said rim and extending into said chamber for engaging saidspring.

ln testimony whereof I have hereunto set my hand.
